I updated everything to the latest Unity Editor. Also realized I had the wrong shaders on my hairs, those are fixed and the hairs look MUCH better!

Dielectric Specular Node
Description
Returns a Dielectric Specular F0 value for a physically based material. The material to use can be selected with the Material dropdown parameter on the Node.
A Common Material type defines a range between 0.034 and 0.048 sRGB values. The value between this range can be selected with the Range parameter. This Material type should be used for various materials such as plastics and fabrics.
You can use Custom material type to define your own physically based material value. The output value in this case is defined by its index of refraction. This can be set by the parameter IOR.

Generated Code Example
The following example code represents one possible outcome of this node per Material mode.
Common
float _DielectricSpecular_Range = 0.5;
float _DielectricSpecular_Out = lerp(0.034, 0.048, _DielectricSpecular_Range);
RustedMetal
float _DielectricSpecular_Out = 0.030;
Water
float _DielectricSpecular_Out = 0.020;
Ice
float _DielectricSpecular_Out = 0.018;
Glass
float _DielectricSpecular_Out = 0.040;
Custom
float _DielectricSpecular_IOR = 1;
float _DielectricSpecular_Out = pow(_Node_IOR - 1, 2) / pow(_DielectricSpecular_IOR + 1, 2);
